This data model is flawed. LDAP is not SQL, arbitrary relations are
poorly supported. Determining wether a user is a member of "some" group
is not efficient in LDAP, as you have to scan the set of all groups,
and then return multiple large group "entries" that match the filter.
If you insist on this design, dump LDAP groups periodically to flat
files, and build an indexed "CDB" or "Berkeley DB" table indexed by
addesses of users who are group members.

It is "possible" to work-around the inevitable multiple result values, but
I am loath to recommend it, so would prefer to not post such a "solution".
The build-a-static-table approach is I think much better.
